Description

Technical Field

[0001] The present disclosure relates to an ultrasonic atomization system that detects the degradation characteristics of ultrasonic vibrators used in a plurality of ultrasonic atomizers and detects the lifespan of the ultrasonic vibrators used in each usage environment.

Background Art

[0002] The performance of an ultrasonic vibrator that ultrasonically vibrates a liquid to atomize it deteriorates over time, resulting in a decrease in atomization efficiency. Although the ultrasonic vibrator with reduced atomization efficiency can be periodically replaced to prevent the decrease in atomization efficiency, the lifespan of the ultrasonic vibrator with reduced atomization efficiency varies greatly depending on the environment in which it is used. Therefore, it is extremely difficult to determine the exact lifespan of an ultrasonic atomization system in various usage environments. The ultrasonic atomizer can set a short lifespan for the ultrasonic vibrator to prevent a decrease in atomization efficiency, but this method will result in replacing ultrasonic vibrators that do not have a decrease in atomization efficiency, increasing the running cost. On the contrary, setting a long lifespan can reduce the running cost, but setting a long lifespan will result in using an ultrasonic vibrator with a decreased atomization efficiency, and the decrease in atomization efficiency cannot be prevented. By detecting the characteristics and lifespan of the ultrasonic vibrator that deteriorates during use and replacing it at the optimal time, it is possible to prevent the decrease in atomization efficiency while preventing the adverse effects of replacing ultrasonic vibrators that do not have a decrease in atomization efficiency.

[0003] The degradation of the ultrasonic vibrator can be detected by various methods. For example, a method of detecting degradation by measuring the change in the impedance of the ultrasonic vibrator has been developed (Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] The deterioration characteristics can be detected from the change in the impedance of each ultrasonic vibrator, and the life of the ultrasonic vibrator can be specified. Therefore, the ultrasonic atomizer is provided with a mechanism for determining the life from the change in the impedance of the ultrasonic vibrator, and by periodically replacing the ultrasonic vibrator with a reduced atomization efficiency, the liquid can be efficiently atomized over a long period without reducing the atomization efficiency. However, for an ultrasonic atomizer provided with a mechanism for detecting the deterioration and life of the ultrasonic vibrator, both the component cost and the assembly cost of the detection mechanism increase, so most ultrasonic atomizers do not have a mechanism for detecting the deterioration and life of the ultrasonic vibrator.

[0006] The deterioration of the ultrasonic vibrator varies depending on various usage environments. The deterioration of the ultrasonic vibrator varies greatly in different usage environments, but has approximately the same properties in the same usage environment. Therefore, if the life of the ultrasonic vibrator for various usage environments can be detected, without providing a mechanism for detecting the deterioration of the ultrasonic vibrator used in the same usage environment, the life can be assumed from the usage environment and replaced periodically to prevent a decrease in atomization efficiency. This ultrasonic atomizer can replace the ultrasonic vibrator with a decreasing atomization efficiency at the optimal usage time without replacing the ultrasonic vibrator with a non-decreasing atomization efficiency, so it has the feature that the ultrasonic vibrator can be replaced at the optimal timing and the ultrasonic atomizer can be operated while maintaining a high atomization efficiency. However, to achieve this, it is necessary to detect in advance the life of the ultrasonic vibrators used in a wide variety of usage environments. Since the ultrasonic vibrator is used in various usage environments to atomize the liquid, to assume the life of the ultrasonic vibrator used in each different usage environment, it is necessary to detect the life of the ultrasonic vibrator for as many usage environments as possible.

[0007] The present disclosure aims to provide an ultrasonic atomization system for detecting the life of an ultrasonic vibrator that can accurately estimate the life of the ultrasonic vibrator for various usage environments by detecting the life of many ultrasonic vibrators used in various usage environments.

Means for Solving the Problems

[0008] An ultrasonic atomization system for detecting the lifespan of an ultrasonic vibrator according to an aspect of the present disclosure includes a plurality of ultrasonic atomizers for atomizing a liquid in each usage environment, and a deterioration detection circuit provided in each ultrasonic atomizer for detecting a deterioration parameter that changes as the ultrasonic vibrator equipped in the ultrasonic atomizer deteriorates, converting the deterioration parameter into a digital signal, and outputting the digital signal. The system also includes a lifespan detection unit connected to the deterioration detection circuit provided in each ultrasonic atomizer via an Internet line for detecting the lifespan of the ultrasonic vibrator equipped in each ultrasonic atomizer from the deterioration parameter output from each deterioration detection circuit. The lifespan detection unit detects the lifespan of the ultrasonic vibrator with respect to the usage environment of each ultrasonic atomizer from the deterioration parameter output from each deterioration detection circuit.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, the present invention will be described in detail with reference to the drawings. In the following description, terms indicating specific directions or positions (for example, "upper", "lower", and other terms including these terms) are used as necessary, but the use of these terms is for facilitating the understanding of the invention with reference to the drawings, and the technical scope of the present invention is not limited by the meanings of these terms. Also, parts denoted by the same reference numerals in a plurality of drawings indicate the same or equivalent parts or members. Furthermore, the embodiments shown below are specific examples of the technical idea of the present invention and do not limit the present invention as follows. Also, the dimensions, materials, shapes, relative arrangements, etc. of the components described below are not intended to limit the scope of the present invention only to those, but are intended to be illustrative unless otherwise specifically described. Also, the content described in one embodiment or example is applicable to other embodiments or examples. Also, the sizes and positional relationships of the members shown in the drawings may be exaggerated for clarity of explanation.

[0012] An ultrasonic atomization system for detecting the life of an ultrasonic vibrator according to an embodiment of the present disclosure includes a plurality of ultrasonic atomizers that atomize a liquid in each use environment, and is provided in each ultrasonic atomizer to detect a deterioration parameter that changes as the ultrasonic vibrator equipped in the ultrasonic atomizer deteriorates, and a deterioration detection circuit that converts the deterioration parameter into a digital signal and outputs it, and is connected to the deterioration detection circuit provided in each ultrasonic atomizer via an Internet line, and from the deterioration parameter output from each deterioration detection circuit, a life detection unit that detects the life of the ultrasonic vibrator equipped in each ultrasonic atomizer. The life detection unit detects the life of the ultrasonic vibrator with respect to the use environment of each ultrasonic atomizer from the deterioration parameter output from each deterioration detection circuit.

[0013] The above ultrasonic atomization system connects a life detection unit to a plurality of ultrasonic atomizers via an Internet line, and the life detection unit detects the life of the ultrasonic vibrator for the usage environment of each ultrasonic atomizer from the deterioration parameters output from the deterioration detection circuit equipped in each ultrasonic atomizer. Therefore, it has the feature of being able to detect the lives of a large number of ultrasonic vibrators in various usage environments. In particular, since this ultrasonic atomization system connects the life detection unit to the ultrasonic atomizer via an Internet line, there are no restrictions on the installation location of the ultrasonic atomizer for detecting the life of the ultrasonic vibrator. Even when the ultrasonic atomizer is installed in a remote location far from the life detection unit, or when a plurality of ultrasonic atomizers are installed separately from each other, it is possible to easily detect the life of each ultrasonic vibrator that atomizes the liquid in various usage environments without having to go to the installation location of the ultrasonic atomizer. The above ultrasonic atomization system can improve the accuracy of estimating the life of the ultrasonic vibrator for a predetermined usage environment by detecting the lives of ultrasonic vibrators for a large number of various usage environments. By detecting the life of the ultrasonic vibrator in a large number of each usage environment, including different usage environments as well as the same or similar usage environments, it can contribute to improving the accuracy of life estimation. For example, by detecting the lives of ultrasonic vibrators for a large number of different usage environments, the influence and tendency on each deterioration parameter can be grasped. Also, by detecting the lives of ultrasonic vibrators for usage environments that are all or partly the same, similar, or slightly different, the influence, tendency, individual differences, fluctuation range, error, etc. on each deterioration parameter can be grasped, and standard numerical values and ranges can be grasped from these data, improving the detection accuracy of the life of the ultrasonic vibrator. By detecting the lives of ultrasonic vibrators for a large number of various usage environments, each deterioration parameter, influence, tendency, etc. can be compared and contrasted, and certain criteria and indicators can be obtained, enabling data accumulation and database creation.

[0014] The ultrasonic atomization system described above has the feature that it can determine the lifespan in each usage environment and utilize the lifespan in each usage environment for various ultrasonic atomizers. For example, in an ultrasonic atomizer that periodically replaces the ultrasonic vibrator, by determining the lifespan in its usage environment, the ultrasonic vibrator can be replaced at an appropriate time, suppressing the decline in atomization efficiency while preventing unnecessary replacements. Moreover, it can be cost-reduced without providing a circuit for detecting the deterioration of the ultrasonic vibrator. In an already installed ultrasonic atomizer, when the ultrasonic vibrator is replaced and it continues to be used in the same usage environment, data such as the deterioration parameters and the specified lifespan of the same ultrasonic atomizer are useful for estimating the lifespan in subsequent times. Also, the data of other ultrasonic atomizers are useful for comparison. Additionally, in a newly installed ultrasonic atomizer, for an ultrasonic vibrator whose lifespan in various usage environments has been determined, without providing a circuit for detecting deterioration, the lifespan, that is, the service life, of the ultrasonic vibrator used in a predetermined usage environment, for example, the same or a similar usage environment, can be accurately determined and estimated. Therefore, without providing a circuit for detecting the lifespan of the ultrasonic vibrator, while reducing the equipment cost, the ultrasonic vibrator is periodically replaced based on the service life specified from the usage environment, suppressing the decline in atomization efficiency while preventing unnecessary replacements. In particular, the above ultrasonic atomization system can be connected to a large number of ultrasonic atomizers without location restrictions via the Internet line to detect the lifespan of the ultrasonic vibrator for each usage environment. Thus, it has the feature that it can determine the lifespan of the ultrasonic vibrator of ultrasonic atomizers used in a wide variety of usage environments, including those installed in remote locations, and reflect and utilize this to more accurately estimate the lifespan in a predetermined usage environment.

[0015] In the ultrasonic atomization system for detecting the lifespan of the ultrasonic vibrator according to other embodiments of the present disclosure, the deterioration detection circuit can convert the deterioration parameter into a digital signal at a predetermined sampling period and transmit it to the lifespan detection unit via the Internet line.

[0016] In the above ultrasonic atomization system, since the deterioration detection circuit periodically outputs the deterioration parameters of the ultrasonic vibrator to the Internet line at a fixed sampling period, the life detection unit has the feature that it can more accurately detect the life of the ultrasonic vibrator. This is because the life detection unit can detect the deterioration parameters output to the Internet line at a fixed sampling period, and grasp, detect, and analyze the deterioration characteristics of the ultrasonic vibrator that deteriorates over time as change values to detect the life. For example, by grasping, detecting, and analyzing the changes in the deterioration parameters, the changes in the specified life, and the factors and degrees of influence affecting them in chronological order, the accuracy of the life can be improved. Also, the factors affecting the life can be specified, and the life range and error range can be narrowed down.

[0017] The ultrasonic atomization system for detecting the life of the ultrasonic vibrator according to other embodiments of the present disclosure can make each ultrasonic atomizer an apparatus for atomizing different liquids.

[0018] In the above ultrasonic atomization system, for ultrasonic atomizers that atomize liquids of different types, for example, liquids different from water, alcohol, etc., a life detection unit is connected via an Internet line, and it has the feature that it can detect the life of the ultrasonic vibrator used for atomizing each liquid. Therefore, from a number of ultrasonic atomizers that atomize different liquids, the life of the ultrasonic vibrator with respect to the type of liquid being atomized can be specified and estimated. Since the life of the ultrasonic vibrator can be estimated from the type of liquid, in ultrasonic atomizers that have already been installed or will be newly set up in the future, when atomizing the same combination of different liquids, for example, in a predetermined liquid, without providing a circuit for detecting the life of the ultrasonic vibrator, the ultrasonic vibrator can be periodically replaced based on the estimated life, which can reduce the deterioration of the atomization efficiency and also prevent the adverse effect of replacing the ultrasonic vibrator unnecessarily.

[0019] The ultrasonic atomization system for detecting the life of the ultrasonic vibrator according to other embodiments of the present disclosure can make each ultrasonic atomizer an apparatus for atomizing liquids at different temperatures.

[0020] The above ultrasonic atomization system has the feature that a number of ultrasonic atomizers with different temperatures of the atomized liquid are connected via an Internet line, and the lifespan of the ultrasonic vibrators used for atomizing liquids with different temperatures can be detected. Therefore, it has the feature that the lifespan of the ultrasonic vibrators with respect to the temperature of the atomized liquid can be estimated from a number of ultrasonic atomizers with different temperatures of the atomized liquid. Since the lifespan of the ultrasonic vibrator can be estimated from the temperature, in ultrasonic atomizers that have already been installed or will be newly set in the future, when atomizing liquids at different temperatures with the same set temperature combination, for example, in a liquid at a predetermined temperature, without providing a circuit for detecting the lifespan of the ultrasonic vibrator, the ultrasonic vibrator can be replaced based on the estimated lifespan, which can reduce the atomization efficiency and prevent the harm of replacing the ultrasonic vibrator unnecessarily.

[0021] The ultrasonic atomization system for detecting the lifespan of ultrasonic vibrators in other embodiments of the present disclosure can make each ultrasonic atomizer an apparatus for atomizing liquids with different viscosities.

[0022] The above ultrasonic atomization system has the feature that a number of ultrasonic atomizers with different viscosities of the atomized liquid are connected via an Internet line, and the lifespan of the ultrasonic vibrators used for atomizing liquids with different viscosities can be detected. Therefore, it has the feature that the lifespan of the ultrasonic vibrators with respect to the viscosity of the atomized liquid can be estimated from a number of ultrasonic atomizers with different viscosities of the atomized liquid. Since the lifespan of the ultrasonic vibrator can be estimated from the viscosity, in ultrasonic atomizers that have already been installed or will be newly set in the future, when atomizing liquids with different viscosities of the same combination, for example, in a liquid at a predetermined viscosity, without providing a circuit for detecting the lifespan of the ultrasonic vibrator, the ultrasonic vibrator can be replaced based on the estimated lifespan, which can reduce the atomization efficiency and prevent the harm of replacing the ultrasonic vibrator unnecessarily.

[0023] The ultrasonic atomization system for detecting the lifespan of ultrasonic vibrators in other embodiments of the present disclosure can make each ultrasonic atomizer an apparatus for atomizing liquids with ultrasonic vibrators of different frequencies.

[0024] The above ultrasonic atomization system can connect a number of ultrasonic atomizers that ultrasonically vibrate and atomize a liquid at different frequencies via an Internet line, and detect the lifespan of the ultrasonic vibrators used for ultrasonically vibrating and atomizing the liquid at different frequencies. Therefore, it is possible to estimate the lifespan of the ultrasonic vibrator with respect to the frequency of ultrasonically vibrating the liquid from a number of ultrasonic atomizers that atomize the liquid with different frequencies of ultrasonic vibration. Since the lifespan of the ultrasonic vibrator can be estimated from the frequency, in existing or newly installed ultrasonic atomizers, for ultrasonic vibrators of a predetermined frequency, for example, when atomizing a liquid at different frequencies of the same combination, it is possible to replace the ultrasonic vibrator based on the estimated lifespan without providing a circuit for detecting the lifespan of the ultrasonic vibrator, thereby reducing the atomization efficiency and preventing the harm of needlessly replacing the ultrasonic vibrator.

[0025] The ultrasonic atomization system for detecting the lifespan of the ultrasonic vibrator according to other embodiments of the present disclosure can be a device that atomizes a liquid with ultrasonic vibrators of different rated outputs for each ultrasonic atomizer.

[0026] The above ultrasonic atomization system can connect a number of ultrasonic atomizers that atomize a liquid with ultrasonic vibrators of different outputs via an Internet line, and detect the lifespan of the ultrasonic vibrators that atomize the liquid with different outputs. Therefore, it is possible to estimate the lifespan from the output of the ultrasonic vibrator from a number of ultrasonic atomizers with different outputs of the ultrasonic vibrator. Since the lifespan of the ultrasonic vibrator can be estimated from the output of the ultrasonic vibrator, in existing or newly installed ultrasonic atomizers, for ultrasonic vibrators of a predetermined rated output, for example, in ultrasonic atomizers of the same combination with different rated outputs, it is possible to replace the ultrasonic vibrator based on the estimated lifespan without providing a circuit for detecting the lifespan of the ultrasonic vibrator of the ultrasonic atomizer, thereby reducing the atomization efficiency and preventing the harm of needlessly replacing the ultrasonic vibrator.

[0027] An ultrasonic atomization system for detecting the lifespan of an ultrasonic vibrator according to other embodiments of the present disclosure is such that each ultrasonic atomizer includes a high-frequency power supply for supplying high-frequency power to the ultrasonic vibrator, and a deterioration detection circuit includes a current detection circuit for detecting the high-frequency current supplied from the high-frequency power supply to the ultrasonic vibrator. The detected current detected by the current detection circuit or a detected value calculated from the detected current can be used as a deterioration parameter to detect the lifespan of the ultrasonic vibrator with respect to the usage environment.

[0028] The above ultrasonic atomization system has the feature that with a simple circuit for detecting the current flowing through the ultrasonic vibrator, the deterioration state of the ultrasonic vibrator can be accurately detected using the detected current or a detected value calculated from the detected current as a deterioration parameter.

[0029] An ultrasonic atomization system for detecting the lifespan of an ultrasonic vibrator according to other embodiments of the present disclosure can use, as the detected value calculated from the detected current, either the impedance of the ultrasonic vibrator or the power supplied from the high-frequency power supply to the ultrasonic vibrator.

[0030] The above ultrasonic atomization system has the feature that the deterioration state of the ultrasonic vibrator can be accurately detected using the impedance of the ultrasonic vibrator or the power supplied from the high-frequency power supply to the ultrasonic vibrator as a deterioration parameter. The above ultrasonic atomization system has the feature that it can detect the current flowing through the ultrasonic vibrator and the supply voltage to calculate the impedance, and accurately detect the lifespan by determining the deterioration state of the ultrasonic vibrator from the change in impedance. The above ultrasonic atomization system has the feature that it can detect the current flowing through the ultrasonic vibrator and the supply voltage to calculate the power supplied from the high-frequency power supply to the ultrasonic vibrator, and accurately detect the lifespan by determining the deterioration state of the ultrasonic vibrator from the change in supply power.

[0031] An ultrasonic atomization system for detecting the lifespan of an ultrasonic vibrator according to other embodiments of the present disclosure is such that the deterioration detection circuit includes a frequency counter for detecting the resonance frequency of the ultrasonic vibrator, and the resonance frequency detected by the frequency counter can be output as a deterioration parameter.

[0032] The above ultrasonic atomization system has the feature that the frequency counter can detect the change over time of the resonance frequency of the ultrasonic vibrator, and can accurately detect the life by determining the deterioration state of the ultrasonic vibrator from the change in the resonance frequency.

[0033] The ultrasonic atomization system for detecting the life of the ultrasonic vibrator according to another embodiment of the present disclosure includes that each ultrasonic atomizer is provided with a high-frequency power supply for supplying high-frequency power to the ultrasonic vibrator, and the deterioration detection circuit is provided with a power consumption detection circuit for detecting the power consumption of the high-frequency power supply. By outputting the power consumption detected by the power consumption detection circuit as a deterioration parameter, the life of the ultrasonic vibrator with respect to the use environment can be detected.

[0034] The ultrasonic atomization system for detecting the life of the ultrasonic vibrator according to another embodiment of the present disclosure includes that the deterioration detection circuit is provided with a vibration sensor for detecting the vibration intensity of the liquid vibrated ultrasonically by the ultrasonic vibrator. By outputting the vibration intensity of the liquid detected by the vibration sensor as a deterioration parameter, the life of the ultrasonic vibrator with respect to the use environment can be detected.

[0035] The ultrasonic atomization system for detecting the life of the ultrasonic vibrator according to another embodiment of the present disclosure includes that the deterioration detection circuit is provided with a mist sensor for detecting the amount of mist generated by the ultrasonic vibration and atomization by the ultrasonic vibrator. By outputting the amount of mist detected by the mist sensor as a deterioration parameter, the life of the ultrasonic vibrator with respect to the use environment can be detected. (Embodiment 1)

[0036] The ultrasonic atomization system 100 shown in the block diagram of FIG. 1 includes a plurality of ultrasonic atomizers 1 connected via the Internet line 6, and a life detection unit 3 of the ultrasonic vibrator 1a connected to the ultrasonic atomizer 1 via the Internet line 6. (Ultrasonic Atomizer 1)

[0037] The ultrasonic atomization system 100 includes a plurality of ultrasonic atomizers 1. Each ultrasonic atomizer 1 ultrasonically vibrates and atomizes the liquid L with an ultrasonic vibrator 1a in each use environment. The plurality of ultrasonic atomizers 1 are installed adjacent to or / and separated from each other. The ultrasonic atomizer 1 is installed away from a life detection unit 3 described later and is connected to the life detection unit 3 via each Internet line 6. The entity using the plurality of ultrasonic atomizers 1, the installation location, and the use environment are not limited. The plurality of ultrasonic atomizers 1 are used by the same or different entities, installed at the same or different locations away from the life detection unit 3, and used in the same or different use environments. In the ultrasonic atomizer 1, the performance of the ultrasonic vibrator 1a that ultrasonically vibrates and atomizes the liquid L deteriorates over time, resulting in a decrease in atomization efficiency. The degree of deterioration of the ultrasonic vibrator 1a varies depending on the use environment. In the ultrasonic atomization system 100, a deterioration detection circuit 2 described later is provided for each ultrasonic atomizer 1, and each deterioration detection circuit 2 is connected to the life detection unit 3 via the Internet line 6. Therefore, in the ultrasonic atomization system 100, a plurality of ultrasonic atomizers 1 installed in remote locations away from the life detection unit 3, such as various locations in Japan, and used in various use environments are connected to the life detection unit 3 through the Internet line 6. Each deterioration detection circuit 2 detects deterioration parameters, and the life detection unit 3 detects the life of the ultrasonic vibrator 1a in the use environment of each ultrasonic atomizer 1. It should be noted that the present disclosure does not specify the structure, shape, size, type, etc. of the ultrasonic atomizer, and includes all ultrasonic atomizers that ultrasonically vibrate and atomize a liquid with an ultrasonic vibrator, including those currently in use and those to be developed in the future. (Life detection unit 3)

[0038] The life detection unit 3 identifies the life, i.e., the service life, of the ultrasonic vibrator 1a of each ultrasonic atomizer 1 based on the deterioration parameters transmitted from each ultrasonic atomizer 1 via the Internet line 6. It is important to connect to a larger number of ultrasonic atomizers 1 with different usage environments and detect the life in each usage environment, and the ultrasonic atomization system 100 of the present disclosure implements this. By connecting to more ultrasonic atomizers 1 and having the life detection unit 3 detect the life of many ultrasonic vibrators 1a based on each deterioration parameter, it becomes possible to accurately estimate the life of various ultrasonic vibrators 1a from the deterioration characteristics of the ultrasonic vibrator 1a in the usage environment of each ultrasonic atomizer 1, and the estimation accuracy of the life can be improved. Also, the error range, influencing factors, etc. can be quantified from the usage environments of various ultrasonic vibrators 1a. Further, by storing, accumulating, and creating a database of a large number of usage environments, deterioration parameters, their combinations, and time-series changes in the storage unit 4 and repeatedly performing comparison, analysis, and update, the accuracy can be further improved. The life detection unit 3 of the ultrasonic atomization system 100 of the present disclosure identifies the life of the ultrasonic vibrator 1a in a large number of diverse usage environments via the Internet line 6. Subsequently, the ultrasonic atomizer 1 to be used can identify and estimate the life, i.e., the service life, of the ultrasonic vibrator 1a in a predetermined usage environment without providing a circuit for detecting the life, and can be periodically replaced at an appropriate time. Note that the identified and estimated life and service life can be indicated by specific numerical values or a predetermined range. The life indicated by a predetermined range can reflect individual differences, errors, usage environments and their changes, influences, detection and estimation accuracy, factors other than the reflected deterioration parameters, etc. (Deterioration detection circuit 2)

[0039] The ultrasonic atomization system 100 in FIG. 1 connects a life detection unit 3 to a plurality of ultrasonic atomizers 1 via an Internet line 6. The life detection unit 3 detects the life of the ultrasonic vibrator 1a equipped in each ultrasonic atomizer 1. The plurality of ultrasonic atomizers 1 atomize the liquid L in their respective usage environments. Each ultrasonic atomizer 1 is provided with a deterioration detection circuit 2 that detects the deterioration parameter of the ultrasonic vibrator 1a. The deterioration detection circuit 2 detects the deterioration parameter that changes as the ultrasonic vibrator 1a deteriorates. The deterioration detection circuit 2 converts the deterioration parameter into a digital signal and outputs it to the Internet line 6. The deterioration detection circuit 2 transmits the deterioration parameter to the life detection unit 3 via the Internet line 6. The Internet line 6 connects the deterioration detection circuits 2 arranged separately to the life detection unit 3. The life detection unit 3 detects the life of the ultrasonic vibrator 1a in the usage environment of each ultrasonic atomizer 1 from the deterioration parameters output from each deterioration detection circuit 2.

[0040] Each ultrasonic atomizer 1 atomizes the liquid L by ultrasonic vibration with the ultrasonic vibrator 1a in its respective usage environment. Each usage environment is determined by the environment, conditions, and situations in which each ultrasonic atomizer 1 is used. Each usage environment has various environments, conditions, and situations that affect the life of the ultrasonic vibrator 1a, such as one or more different conditions, one or more similar conditions, or one or more identical conditions. The conditions under which each ultrasonic vibrator 1a ultrasonically vibrates the liquid L, that is, the usage environment of the ultrasonic vibrator 1a, is specified by the use of each ultrasonic atomizer 1. The usage environment of the ultrasonic vibrator 1a affects the life of the ultrasonic vibrator 1a, that is, the service life. The ultrasonic atomization system 100 in FIG. 1 connects a life detection unit 3 to a plurality of ultrasonic atomizers 1 that atomize the liquid L in their respective usage environments via an Internet line 6, and the life detection unit 3 detects the life of the ultrasonic vibrator 1a used in various usage environments.

[0041] Specific examples of the usage environment of each ultrasonic atomizer 1 include, for example, the type of the liquid L that is ultrasonically vibrated and atomized, the temperature of the liquid L, the viscosity of the liquid L, the frequency of the ultrasonic vibrator 1a that ultrasonically vibrates the liquid L, the rated output of the ultrasonic vibrator 1a, etc. However, the present disclosure does not specify or limit the usage environment in which the ultrasonic atomizer 1 connected via the Internet line 6 atomizes the liquid L to the above environments, and other conditions, environments, situations, etc. that affect the lifespan of the ultrasonic vibrator 1a can also be used as the usage environment. For example, the amount of the liquid, the number of installed ultrasonic vibrators, the arrangement, the structure and mechanism of the ultrasonic atomizer, the usage time, the usage frequency, the degree of deterioration, etc., and external conditions that affect the lifespan of the ultrasonic vibrator are also included. Also included are combinations of a plurality of conditions and environments. (Environment specifying unit 5)

[0042] The environment specifying unit 5 specifies the usage environment of the ultrasonic atomizer 1. The environment specifying unit 5 specifies the usage environment of each ultrasonic atomizer 1 and inputs it to the lifespan detection unit 3. The lifespan detection unit 3 detects the lifespan of the ultrasonic vibrator 1a in each input usage environment. The usage environment of the ultrasonic atomizer 1 includes a constant usage environment in which the environment, conditions, situations, etc. do not change or remain within a predetermined range, and a usage environment in which the environment, conditions, situations, etc. change as time passes. The constant usage environment is, for example, the type of the atomized liquid L, the frequency for ultrasonically vibrating the liquid L, the rated output of the ultrasonic vibrator 1a, etc.

[0043] The constant usage environment that does not change can be specified by inputting it to the environment specifying unit 5 or directly to the lifespan detection unit 3 via the input means without being detected and specified by a sensor or the like of the ultrasonic atomizer 1. The usage environment input from the input means to the environment specifying unit 5 can be input to the lifespan detection unit 3 via the Internet line 6, or the input means can be directly connected to the lifespan detection unit 3 without passing through the Internet line 6 for input. As the input means, for example, a keyboard, a changeover switch, a touch panel, etc. can be used.

[0044] The changing usage environment can be identified by the sensors and detection devices of the environment identification unit 5 in the ultrasonic atomizer 1. The changing usage environment is, for example, the temperature and viscosity of the liquid L to be atomized. The environment identification unit 5 of the ultrasonic atomizer 1 that atomizes the liquid L in a changing usage environment detects the changing usage environment, such as temperature and viscosity, at a fixed sampling period, and outputs the temperature and viscosity as environment signals. The environment identification unit 5 outputs the environment signal to the Internet line 6 via the I / O circuit. The environment signal output to the Internet line 6 is transmitted to the life detection unit 3. The life detection unit 3 of the ultrasonic atomizer 1 that atomizes the liquid L in a changing usage environment can identify the life of the ultrasonic vibrator 1a using the average value of the usage environment as the usage environment, and can also identify the life of the ultrasonic vibrator 1a using the changing temperature range and viscosity range as the usage environment.

[0045] For example, the environment identification unit 5 of the ultrasonic atomizer 1 that atomizes the liquid L with a changing temperature includes a temperature sensor that detects the temperature of the liquid L being ultrasonically vibrated, and an A / D converter 23 that converts the output signal of the temperature sensor into a digital signal at a predetermined sampling period. This environment identification unit 5 converts the temperature of the liquid L to be atomized into a digital signal and outputs it to the Internet line 6 as an environment signal.

[0046] Also, the environment identification unit 5 of the ultrasonic atomizer 1 in which the ultrasonic vibrator 1a atomizes liquids L with different viscosities includes a viscosity sensor that detects the viscosity of the liquid L being vibrated by the ultrasonic vibrator 1a, and an A / D converter 23 that converts the output signal of this viscosity sensor into a digital signal at a predetermined sampling period. This environment identification unit 5 converts the viscosity of the liquid L to be atomized into a digital signal and outputs it to the Internet line 6 as an environment signal.

[0047] The usage environment of the ultrasonic vibrator 1a includes, for example, the type of the atomized liquid L, the temperature of the liquid L, the viscosity of the liquid L, the frequency of the ultrasonic vibrator 1a that ultrasonically vibrates the liquid L, the rated output of the ultrasonic vibrator 1a, etc. However, any one of these usage environments, for example, the temperature or the type of the liquid L, etc., can be used to specify the lifespan of the ultrasonic vibrator 1a. Also, it is possible to specify the lifespan of the ultrasonic vibrator 1a in a plurality of usage environments that combine a plurality of usage conditions such as the type of the liquid L and the temperature or / and viscosity. The ultrasonic atomization system 100 that specifies the lifespan from a plurality of usage environments including the type of the liquid L, the temperature, etc., can more accurately specify the lifespan of the ultrasonic vibrator 1a. The ultrasonic atomization system 100 that specifies the lifespan in a plurality of usage environments inputs the plurality of usage environments into the lifespan detection unit 3. The lifespan detection unit 3 detects the degradation parameter of the ultrasonic vibrator 1a in the plurality of input usage environments to detect the lifespan. (Example of the degradation detection circuit 2)

[0048] The degradation detection circuit 2 detects, as a degradation parameter, a numerical value that changes as the ultrasonic vibrator 1a degrades, and detects the degradation state of the ultrasonic vibrator 1a. The ultrasonic atomization system 100 includes a degradation detection circuit 2 in each ultrasonic atomizer 1 that detects the degradation of the ultrasonic vibrator 1a in each usage environment. For example, the degradation detection circuit 2 can detect, as a degradation parameter, the high-frequency current that changes as the ultrasonic vibrator 1a degrades, that is, the current value supplied from the high-frequency power supply 11 to the ultrasonic vibrator 1a. The degradation detection circuits 2 in FIGS. 2 and 3 include a current detection circuit 20 that detects the detection current from the high-frequency power supply 11 flowing through the ultrasonic vibrator 1a, and an A / D converter 23 that converts the detection current detected by the current detection circuit 20 into a digital signal. The A / D converter 23 converts it into a digital signal at a predetermined period and outputs the degradation parameter of the digital signal to the Internet line 6.

[0049] As shown in FIG. 2, the current detection circuit 20 can be realized by a current detection resistor 21, a differential amplifier 22A, and a rectifier circuit 22B. The current detection circuit 20 in this figure connects the current detection resistor 21 in series with the ultrasonic vibrator 1a, amplifies the voltage across both ends of the current detection resistor 21 with the differential amplifier 22A, and converts the alternating current output from the differential amplifier 22A into direct current with the rectifier circuit 22B and outputs it. The deterioration detection circuit 2 converts the analog signal output from the current detection circuit 20 into a digital signal with the A / D converter 23 and outputs it as a deterioration parameter.

[0050] As shown in FIG. 3, furthermore, the current detection circuit 20 can be realized by a transformer 24, a differential amplifier 22A, and a rectifier circuit 22B. The current detection circuit 20 in this figure connects the primary coil 24a of the transformer 24 in series with the ultrasonic vibrator 1a, amplifies the voltage induced in the secondary coil 24b with the differential amplifier 22A, and converts the output of the differential amplifier 22A into direct current with the rectifier circuit 22B and outputs it. The deterioration detection circuit 2 converts the analog signal output from the rectifier circuit 22B into a digital signal with the A / D converter 23 and outputs it as a deterioration parameter.

[0051] As shown in FIG. 4, the deterioration detection circuit 2 can also output, as a deterioration parameter, a detection value calculated from the detection current of the ultrasonic vibrator 1a detected by the current detection circuit 20. The deterioration detection circuit 2 that calculates the detection value calculated from the detection current shown in FIG. 4 includes an arithmetic circuit 27 that calculates the detection value from the detection current. Since the detection value calculated from the detection current can use the impedance of the ultrasonic vibrator 1a or the supply power supplied from the high-frequency power supply 11 to the ultrasonic vibrator 1a, the arithmetic circuit 27 calculates the impedance of the ultrasonic vibrator 1a or the supply current supplied from the frequency power supply 11 to the ultrasonic vibrator 1a from the detection current. The arithmetic circuit 27 that calculates the impedance of the ultrasonic vibrator 1a shown in FIG. 4 can calculate the impedance (Ω) with the following formula from the supply voltage (V) and current (I) of the ultrasonic vibrator 1a. Impedance (Ω) = Supply voltage (V) / Current (I)

[0052] The current of the ultrasonic vibrator 1a, that is, the current flowing through the ultrasonic vibrator 1a, can be detected by the current detection circuit 20. The supply voltage supplied from the high-frequency power supply 11 to the ultrasonic vibrator 1a can be specified from the voltage, the output voltage of the high-frequency power supply 11. Since the high-frequency power supply 11 does not substantially fluctuate due to the current flowing through the ultrasonic vibrator 1a, the rated output voltage of the high-frequency power supply 11 becomes the supply voltage of the ultrasonic vibrator 1a.

[0053] The deterioration detection circuit 2 in FIG. 4 can also detect the supply power supplied to the ultrasonic vibrator 1a from the detected current as a deterioration parameter. This deterioration detection circuit 2 can calculate the supply power supplied from the high-frequency power supply 11 to the ultrasonic vibrator 1a, that is, the supply power (W) to the ultrasonic vibrator 1a, by the arithmetic circuit 27 and detect it as a deterioration parameter. The arithmetic circuit 27 can detect the supply power (W) from the supply voltage (V) and current (I) to the ultrasonic vibrator 1a by the following formula. Supply power (W) to the ultrasonic vibrator 1a = Supply voltage (V) × Current (I)

[0054] As shown in FIG. 5, the deterioration detection circuit 2 can detect the resonance frequency of the ultrasonic vibrator 1a as a deterioration parameter. Since the ultrasonic vibrator 1a deteriorates and the resonance frequency changes, the deterioration detection circuit 2 can detect the resonance frequency of the ultrasonic vibrator 1a and output the resonance frequency as a deterioration parameter. The ultrasonic vibrator 1a can efficiently atomize the liquid L when high-frequency power of its own resonance frequency is supplied. Therefore, the high-frequency power supply 11 that uses the ultrasonic vibrator 1a with high efficiency is provided with a frequency control circuit that adjusts the frequency of the output high-frequency power to the resonance frequency of the ultrasonic vibrator 1a. In this ultrasonic atomizer 1, the deterioration detection circuit 2 detects that the resonance frequency of the ultrasonic vibrator 1a fluctuates over time by the frequency counter 26, and can determine the life of the ultrasonic vibrator 1a. The frequency counter 26 detects the resonance frequency of the ultrasonic vibrator 1a as a deterioration parameter, and outputs the detected deterioration parameter to the Internet line 6.

[0055] As shown in FIG. 6, the deterioration detection circuit 2 can further detect the power consumption of the high-frequency power supply 11 that supplies high-frequency power to the ultrasonic vibrator 1a and use it as a deterioration parameter. The reason why the deterioration of the ultrasonic vibrator 1a can be detected by detecting the power consumption of the high-frequency power supply 11 is that as the ultrasonic vibrator 1a deteriorates, its power consumption changes, and thus the power supplied from the high-frequency power supply 11 to the ultrasonic vibrator 1a changes. This deterioration detection circuit 2 includes a power consumption detection circuit 27 that detects the power consumption (W) of the high-frequency power supply 11. The power consumption detection circuit 27 can detect the input voltage (V) and input current (I) of the high-frequency power supply 11 and detect the power consumption (W) of the high-frequency power supply 11 using the following formula. Power consumption (W) of the high-frequency power supply 11 = Input voltage (V) × Input current (I)

[0056] Furthermore, the deterioration detection circuit 2 can detect the vibration intensity of the liquid L vibrated ultrasonically by the ultrasonic vibrator 1a and use it as a deterioration parameter. This is because as the ultrasonic vibrator 1a deteriorates, the vibration intensity of the liquid L vibrated ultrasonically changes. The deterioration detection circuit 2 in FIG. 7 includes a vibration sensor 28 that detects the vibration intensity of the liquid L vibrated ultrasonically by the ultrasonic vibrator 1a. By outputting the vibration intensity of the liquid L detected by the vibration sensor 28 as a deterioration parameter to the Internet line 6 via a vibration detection circuit, the lifespan of the ultrasonic vibrator 1a with respect to the usage environment can be detected. The vibration sensor 28 includes all sensors, devices, etc. that can detect the vibration intensity of the liquid L vibrated ultrasonically and output the change in the vibration intensity as a deterioration parameter of the ultrasonic vibrator 1a. Its configuration, structure, etc. are not specified and include sensors, devices, etc. currently or developed in the future.

[0057] Furthermore, the deterioration detection circuit 2 can detect the generation amount of mist that is ultrasonically vibrated and atomized by the ultrasonic vibrator 1a and use it as a deterioration parameter. This is because when the ultrasonic vibrator 1a deteriorates, the generation amount of mist that is ultrasonically vibrated and atomized changes. The deterioration detection circuit 2 shown in FIG. 8 includes a mist sensor 29 that detects the generation amount of mist that is ultrasonically vibrated and atomized by the ultrasonic vibrator 1a. By outputting the generation amount of mist detected by the mist sensor 29 as a deterioration parameter to the Internet line 6 via the mist detection circuit, the lifespan of the ultrasonic vibrator 1a in the usage environment can be detected. The mist sensor 29 includes all sensors, devices, etc. that can detect the generation amount of mist that is ultrasonically vibrated and atomized by the ultrasonic vibrator 1a and output the change in the generation amount of mist as a deterioration parameter of the ultrasonic vibrator 1a. The configuration, structure, etc. are not specified and include sensors, devices, etc. that are currently or will be developed in the future.

[0058] The deterioration detection circuit 2 can convert the deterioration parameter into a digital signal at a predetermined sampling period, output it to the Internet line, and transmit it to the lifespan detection unit 3. The sampling period at which the deterioration detection circuit 2 converts the deterioration parameter into a digital signal and outputs it can be, for example, from 1 second to several days, preferably from 1 hour to 1 day. The deterioration detection circuit 2 can also calculate the average value of a plurality of deterioration parameters detected in a predetermined time period and transmit the average value of the deterioration parameters to the lifespan detection unit 3. This method can suppress the variation in measurement error and detect the deterioration parameter with higher accuracy and transmit it to the lifespan detection unit 3.

[0059] The life detection unit 3 sequentially detects the deterioration parameters output from the deterioration detection circuit 2 of each ultrasonic atomizer 1 in time series, and based on the deterioration parameters output from each deterioration detection circuit 2, detects the life of the ultrasonic vibrator 1a equipped with each ultrasonic atomizer 1. In order to detect the deterioration parameters from the deterioration detection circuit 2 of each ultrasonic atomizer 1, the life detection unit 3 is sequentially connected to the deterioration detection circuit 2 of each ultrasonic atomizer 1 via the Internet line 6 to detect the deterioration parameters. In order to sequentially connect to the deterioration detection circuit 2 of each ultrasonic atomizer 1 and detect the deterioration parameters, the life detection unit 3 outputs a trigger signal for prompting the output of the deterioration parameters to the deterioration detection circuit 2 of each ultrasonic atomizer 1 in sequence. The deterioration detection circuit 2 of each ultrasonic atomizer 1 detects the trigger signal and outputs the deterioration parameters to the life detection unit 3.

[0060] The deterioration detection circuit 2 of each ultrasonic atomizer 1 temporarily stores in the memory the deterioration parameters of the ultrasonic vibrator 1a detected at a predetermined sampling period. The deterioration detection circuit 2 detects the trigger signal from the life detection unit 3 and outputs the deterioration parameters stored in the memory to the life detection unit 3. The memory of each deterioration detection circuit 2 can store the deterioration parameters in a predetermined time period, for example, the deterioration parameters output by the deterioration detection circuit 2 in one day. In this ultrasonic atomization system 100 equipped with the deterioration detection circuit 2, the life detection unit 3 can output a trigger signal to the life detection unit 3 via the Internet line 6, for example, once a day. Each time the deterioration detection circuit 2 detects a trigger signal via the Internet line 6, it outputs the deterioration parameters stored in the memory to the life detection unit 3 via the Internet line 6. The life detection unit 3 determines the deterioration state of the ultrasonic vibrator 1a equipped with the ultrasonic atomizer 1 that output the deterioration parameters based on the deterioration parameters transmitted from the life detection unit 3, and detects the life. This ultrasonic atomization system 100 outputs a trigger signal to each ultrasonic atomizer 1 in sequence every day, detects the deterioration parameters from the deterioration detection circuit 2 of each ultrasonic atomizer 1, and detects the life of the ultrasonic vibrator 1a of each ultrasonic atomizer 1 from the deterioration parameters.

[0061] The life detection unit 3 detects the life of the ultrasonic vibrator 1a, that is, the service life, from the change in the deterioration parameter. As the ultrasonic vibrator 1a is used, the atomization efficiency for atomizing the liquid L, that is, the amount of atomization per unit time, decreases and the deterioration parameter changes. In order to specify the life with respect to the deterioration parameter, the control ultrasonic vibrator 1a is operated for a long time, and the deterioration parameter of the ultrasonic vibrator 1a at the timing when the amount of atomization reaches the minimum value is measured, and this deterioration parameter is used as the life detection parameter. The life detection unit 3 determines that the state in which the deterioration parameter detected by the deterioration detection circuit 2 changes to the life detection parameter is the life of the ultrasonic vibrator 1a, that is, the service life. The life detection parameter can also be specified by measuring the deterioration parameter of the ultrasonic vibrator 1a whose atomization amount has already decreased to the set value. This ultrasonic atomizer 1 can detect the life detection parameter of the ultrasonic vibrator 1a without operating until the atomization amount decreases.

[0062] The ultrasonic atomization system 100 of the present disclosure can detect the current flowing through the ultrasonic vibrator 1a and use the detected value calculated from the detected current as the deterioration parameter. However, in the ultrasonic vibrator 1a in which the atomization amount of the liquid L decreases and the current value decreases as the operation time elapses, for example, the minimum current value is set as the life detection parameter, and the state in which the current value of the deterioration parameter becomes the minimum current value of the life detection parameter can be determined as the life of the ultrasonic vibrator 1a.

[0063] The above ultrasonic atomization system 100 specifies the life of the ultrasonic vibrator 1a, that is, the service life, with respect to the use environment, from a plurality of ultrasonic atomizers 1 connected via the Internet line 6. The ultrasonic vibrator 1a for which the life with respect to the use environment has been specified can be used and replaced without subsequently providing a circuit for detecting the life of the ultrasonic vibrator 1a, and can also be used in other ultrasonic atomizers 1 and replaced at the specified service life, so as to operate economically without reducing the atomization efficiency and without unnecessarily replacing the ultrasonic vibrator 1a whose atomization efficiency does not decrease, and to efficiently atomize various liquids L over a long period of time.
